A MAX17043 fuel gauge is adopted in this product for accurate power detection. Besides, we also employs an on-board microcontroller (MCU) for data processing. In this way, Raspberry Pi board is able to get information of power capacity and battery voltage directly via I2C communication. The 5 on-board LEDs for the shield could show the status of the battery capacity visually without programming. We adopted an excellent power management solution in this Raspberry Pi UPS HAT. Over 90% power conversion efficiency and non-dioded design make the shield able to keep low heating temperature even under continuous high load operation of Raspberry Pi.
1.3.7V Lithium Battery is not included in the package due to transportation constraints
2.Please use 3.7V Lithium Battery that meets standard specification
3.Please note that there would be a certain degree of heating in the power source area of the product during operation, you can never be too careful in use.
4.The product V1.0 and Raspberry Pi 3B+ donأ¢â‚¬â„¢t fit together in the hardware structure, so V1.0 is not suitable for Pi 3B+ board.
